    text
    copied!<p>I have some code that allows me to drag and drop a hyperlink from a webpage onto a windows form, and it seperates the URL and the Title and puts them in two different text boxes.</p> <p>This works on windows XP fine, but on windows 7 it no longer works. I'm not sure where the difference lies.</p> <pre><code>object data = e.Data.GetData("UniformResourceLocator"); </code></pre> <p>data will always be null, but when i use</p> <pre><code> string[] fmts = e.Data.GetFormats(); </code></pre> <p>one of fmts will always be UniformResourceLocator, along with a bunch of other ones that I can never seem to get any data from. If anyone has an resources to point me to or something I would greatly appreciate it, this is really confusing for me.</p> <p>Thanks.</p> <p>UPDATE:added method code that used to work</p> <pre><code> string hyperLinkUrl = null; string hyperLinkText = null; hyperLinkUrl = e.Data.GetData(typeof(string)) as string; // some browser deliver url and text // in UniformResourceLocator (Firebird) string[] tokens = null; if (hyperLinkUrl != null) { tokens = hyperLinkUrl.Split('\n'); } if (tokens != null &amp;&amp; tokens.Length &gt; 1) { hyperLinkUrl = tokens[0]; hyperLinkText = tokens[1]; } // we have to read FILEGROUPDESCRIPTOR to get the text (IE) else { System.IO.Stream ioStream = (System.IO.Stream)e.Data.GetData("FileGroupDescriptor"); byte[] contents = new Byte[512]; try { ioStream.Read(contents, 0, 512); } catch (Exception x) { } ioStream.Close(); System.Text.StringBuilder sb = new System.Text.StringBuilder(); //The magic number 76 is the size of that part of the //FILEGROUPDESCRIPTOR structure before // the filename starts - cribbed //from another usenet post. for (int i = 76; contents[i] != 0; i++) { sb.Append((char)contents[i]); } if (!sb.ToString(sb.Length - 4, 4).ToLower().Equals(".url")) { throw new Exception("filename does not end in '.url'"); } hyperLinkText = sb.ToString(0, sb.Length - 4); } tbLinkTitle.Text = hyperLinkText; tbLinkAddress.Text = hyperLinkUrl; </code></pre>
